Traffic Safety

Traffic Safety

•Do not use an earphone/headphones with your scanner when operating a motor vehicle or riding a bicycle in or near traffic. Doing so can create a traffic hazard and could be ille- gal in some areas.

•If you use an earphone/headphones with your scanner while riding a bicycle, be very careful. Do not listen to a continu- ous transmission. Even though some earphones/head- phones let you hear some outside sounds when listening at normal volume levels, they still can present a traffic hazard.

CONNECTING AN EXTENSION SPEAKER

In a noisy area, an amplified extension speaker (available at your local RadioShack store) positioned in the right place, might provide more comfortable listening.

Plug the speaker cable’s 1/8-inch (3.5-mm) plug into your scan- ner’s jack.

Note: Connecting an external speaker disconnects the scan- ner’s internal speaker.
